The Controlled-U and Unitary Transformation in Two-Qudit

Kunio Funahashi

abstract: We concretely construct an extension of the controlled-U gate in qudit from some elementary gates. We also construct unitary transformation in two-qudit by means of the extended controlled-U gate and show the universality of it.
